Hi I’m here at Fanfest and noticed something in Lore Book II that I think might play into Shadowbringer’s teaser.
There’s a page for each dungeon and a blurb for the final bosses. For Kuribu it says the statue is modeled after a transcendental being from another plane.
There are a few more likey answers: cinema team not always being 100% accurate; representation of Light, etc; but it’s fun to think about seven months out
